A simple model for nonlinear finite element analysis of 3-dimensional reinforced concrete shear wall structures is proposed in this study. The constitutive model is formulated on the basis of the nonlinearity of concrete and reinforcement. It considers the tension stiffening in tension and the degradation of stiffness and strength in compression based on Collins' theory. Reinforcement is modeled by a bi-linear relationship. The model proposed herein is effective for nonlinear analysis of 3-D RC shear wall structures subjected to not only one-directional but also two-directional cyclic loads. It is applicable to the nonlinear analysis of both reactor buildings and other structures such as 3-dimensional shear walls with L-shaped section or H-shaped section and the shear core walls of buildings. It will also be extended to dynamical nonlinear finite element analysis of 3-dimensional reinforced concrete shear wall system in the near future.
